As of today, we're just 140 days away from the release of the 1940 US census on April 2, 2012! This release is historic for a number of reasons, first and foremost is that it will be the first census released as free digital images at the National Archives website. The images will be there, but until the census is indexed you'll have to browse the images to find the families you're interested in. FamilySearch is now recruiting volunteers to help with the indexing of over 132 million names. You can sign up here. And you can even pick the state you're most interested in! I picked Michigan. (You had to ask?)
